for the marinating sauce:
For a start, clean the mangetout and the turnips and boil them. Aside, prepare a marinating sauce for the mullets, mixing the ingredients and boiling them.
Then, place the mullets, well spaced, on a baking pan and pour the hot marinating sauce on top of them, distributing it evenly.
While the mullets absorb the sauce, stir-fry all the vegetables: mangetout, mushrooms, turnips and as much salt as necessary.
Place the vegetables on a dish, then put marinated mullets on top. Use the (filleted or sliced) salami to make a rose next to the mullets.
